A Sword Forged from the Source, Capable of Killing All Things

In the era of supernatural awakening, Jiang Wuyan, a low-level boy, accidentally awakened a suspected rule-level "cutting" power, but was forced to hide his strength and deal with ordinary life and hidden crises as a B-level "sword master". Just when he thought he could protect his sister Xiaoya with the seed plan of "Deep Blue Academy", a conspiracy against him quietly came - the dark forces in the north used the "grey erosion" incident as bait to lure the tiger away from the mountain and kidnapped Xiaoya. Jiang Wuyan was forced to face the hidden truth: his power had the same origin as the "grey thread" that annihilated three cities seventeen years ago, and his sister was actually the "key" that the enemy fought for. In order to save his loved ones, he must control the dangerous "Sword of Destiny" in his body, cut through the fog, and face the dark nature of the world.
